Application does not launch on debugging message

[asitemade4u]

• Debian 10 Buster, last version
• Desktop App
• The application does not start.

Here are the measures I have taken:

1. change the port in config file > no result
2. uninstall app completely and remove all configuration files everywhere > no
3. execute from the Terminal. It gives this error + debugging message: [11901:0320/145359.007916:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /opt/Ten Hands/chrome-sandbox is owned by root and has mode 4755. Trace/breakpoint trap
4. I then follow the advice and change both owner and mode of chrome-sandbox > it sends the debugging message Trace/breakpoint trap only now and the application still does NOT start.
5. I recently switched to Debian from Ubuntu 18.10. It was working well on Ubuntu.

I'll install and test in Debian this weekend.
